  • Description

    The latest PJB D-400 answers the quest for a powerful, high-fidelity and lightweight amplifier all in a beautifully designed package. Phil Jones Bass also wanted to make it completely noise free; so they use the latest high-efficiency class D amplifier designs to eliminate the need for a fan. As a result, this amp is totally quiet, runs cool and therefore it's extremely reliable. The chassis are precision made from aircraft grade anodized black aluminum. The D-400 comes with a padded soft gig bag to preserve its beauty over years of usage. This amp is standard 1U to allow the possibility of being rack mounted.

    Weighing in at less than 3 pounds, the D-400 serves up 350 watts of power and comes loaded with pro-grade features including an onboard 5-Band EQ for superior sound shaping, a built-in limiter, an integrated headphone jack, an FX loop, and speaker, preamp and D.I. outputs.
